Application iled'Jannary 3D, 1924, Serial No.

The invention relates to an agricultural machine for drilling seeds or fertilizer or al mixture of botli,'and comprises multiple distributing means and means for measuring the materials as well as for feeding the saine uniformly to the single drills of the machine rlhhe invention also relates to means for regulating the depth at which the different kinds of seeds must be placed and to plant the seeds at the proper depth regardless of the unevennesses of the ground.

The invention also relates to means for regulating the depth of the diferent drills7 so that each drill can be regulated independently of the others.

' According to the invention, the material te., be drilled or distributed drops intermittently in measured quantities from two hopperspjarranged one` on either end of the machine, upon two oscillating tables which extend from the two. hoppers to the middle of the machine, these tables having the same number of grooves as there are drills on the machine, and each groove communicating with a small tube whichl conducts the seed or fertilizer toL a point 1oehind the corresponding drill. i g

The invention is illustrated by way of example in the accompanying drawings', in which Figure 1 is a rear elevation of the improved drilling and fertilizing machine.

Fig. 2 is a vertical section taken on the line 2 2l of Figure 1.

Figs. -3 and 4t are a side view and a plan view respectively of the feeding table.

Fig. 5 is a section taken on the line 5-5 of Figure 1, and

Fig. 6 is a 'section talren on the line 6--6 of Fi 5.

Ign these figures, 1 is a hopper to receive the material to be drilled, and 2 is the casing of a measuring device. The hopper and measuring device are carried by supports 3. Themeasuring deviceis provided with a` fixed wall 4 atV or near the center line of the hopper cooperating with an adjustable wall 5 to form a measuring compartment 13. rlhe wall 5 can be moved by a screwed spindle 6 Y 'that passes through the inner end of the casing 2 and terminates in a handwheel 7. By rotating the hand wheel 7, the size of the measuring compartment 13 can be regulated` Y A series of graduation marks may be placed er the 689,562, and in Great Britain March 1,7,l 1323.

receiver together with an indicator on the handwheel, to aid the operator to. read by the graduations the volume of the measuring receiver with reference to the position of the hand wheel and to determine the quantity of seed toy be employed for a. determined piece of ground to, be drilled and fertilized. Arranged respectively above and below the members Lland 5, are two parallel plates 8 andV 9, forming a. slide valve, and these plates are fastened to a member 1 0. Theupper plate 8 has an opening 11 and the lower plate an opening 12, which openings are out of vertical alignment-` soy that during reciprocation of the plates, the openings successively register with the compartment 13, whereby material is first admitted to Said compartment through the aperture 1 1 and subsequently discharged through the aperture 12. Each of the members 104 is connected to one end of a doublefarmed lever` 14, which is fulcrumed at 15, upon a bracket 1GV fastened on one of the supports 3. The lever y1lcarries a tooth 1 7 which is kept by the spiral spring 18 in contact with a circular cam of an actuating member 19. fastened to the wheel of the machine, so that at the rotation of the wheel, the cam effects intermittent movement of the tooth andY therewith the plates 8 and 9 in one direction, causing a determined quantity of Vseed to drop from the hopper into the. measuring space 13, in which the seed will remain until the cam ceases to influence the tooth 17 and the plates 8 and 9 are moved in the opposite direction by the spring 18. At this time the seed in compartment 13 will drop through aperture 12 onto a transporting table 20. The transporting table extends between the supports 3 and is of the same width as the measuring space 13. The table, as best shown in Figs. l and 5, is provided on its upper side with as many grooves E20EL as there are drills to be fed, so that the same quantity of material is fed to each drill. Every machine has two feeding devices and two transporting tables. The

grooves conduct'the seed to small tubes 21 which discharge into members 22 having drills 22 at their lower ends. To permit this, the length of the groves gradually diminishes from the centre of the machine toe wards the outside. Each table is supported foy two arms 23 which are both connected atv 24 to the table and at 251' the frame of the machina In order to oscillate the table, the latter is provided with a tooth 2G which is constantly pressed b v a spiral spring QT against the circular corrugated 'face of an actuating member 2S fastened to and coaxially' arranged with the wheel ot' the machine, so that at the rotation of the wheel, the cam intermittently moves the tooth Q6 and imparts to the table an oscillating movement around the tulcrums Q5. rEhe table at each oscillation also receives a certain inclination. Due to this, the seed or fertilizing material at each oscillation is advanced progressively in the grooves ot the table until the seed reaches the vertical tubes il which conduct the material behind the drill members Rollers Q9 serve to cover the seed an Al compress the ground above the seed laid in the furrow. The drill members 22 are made ot' bent sheet metal and are loosely mounted on the fixed machine shatt 30. A lever 3l is rigidly connected with the machine shaft S0, and is provided at its free end with a pivot for another lever 33. The lever receives one end of the adjustable rod 3st, the other end ot which is connected by a forl 35 with the roller Q9. A. radius rod 3G is pivoted at one end 37 upon the drill member 2Q and at its other end to the fork A telescopic connecting rod 3S is surrounded by a` spiral spring and connects the joints 32 and 3T.

Ey this system of levers, it is possible it there is an unevenness of the ground which tends to litt any ot the rollers 29, for the roller to move backward and thereby rotate around the fulerum 32, pulling with it to a certain extent the drill 22. In this rotation, the depth ot' the 'furrow o'l the drill remains about the same as bel'ore the rotation has taken place. VIhe spring 23) liecomes compressed and then so acts upon the drill, that on account of the connecting rod 36 the drill cannot penetrate further into the ground until the roller 2f) has again dropped. rl`he depth ot the Vturrows can be regulated by lengthening or shortening the rods 3l upon the levers $33. the rods 3lin every position being locked to the levers 33 by the locking rings J0. 2r lever ll is lived to the shaft 30, and can be actuated li: the operator ot the machine from the seat 42, in order to raise the levers 351 and thereby lift the drills Q2 trom the ground when discontinuing operation.

lVhat I claim is A multiple drilling and Yfertilizer machine comprisingp; a Vl'rame, hoppers mounted at each end ot said frame, two oscillatingI transporting tables extending trom the ends ot the trame to the center thereof, each table extending beneath one ot the hopper-s and being provided with a number ot grooves successively decreasing in length toward the center, measuring means between each hopper and the table beneath the same, means for actuating the measuring means to Cause the same to intern'iittently deposit material 'from the hopper into the grooves of the table beneath, and drilling tubes arranged to receive material discharged from the grooves.

In testimony whereof I have signed my.

name to this specification.
